Swelling after fat grafting and general weight gain, I'm 40 years old.

I had reconstruction w/ implants &months later fat grafting after a bilateral mastectomy chemo & radiation. Love way breasts look but have good bit of swelling from the lipo- (flanks)-over a month out. Feels little numb and swollen till hurts little to the touch. I'm 5'7 and usually 135 pounds but since this surgery have been at 150 (i only see this on scale) is there anything i can do to reduce swelling and get rid of what i'm hoping is post surgery (trauma?) weight?
